Build fail on Debian testing + clang

[Julien Nabet]

Hello,

On pc Debian x86-64 with master sources updated today, I did:

make clean && make

and got:

Traceback (most recent call last):
   File "/usr/bin/meson", line 24, in <module>
     from mesonbuild import mesonmain
ModuleNotFoundError: No module named 'mesonbuild'
make[1]: ***

meson version: 1.7.0

ninja version: 1.12.1

I tried to build locally an hello world with meson/ninja, it was ok

Any idea how to fix this?
